Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | Interior view of the Schadels | Portrats of two men | A rock gorge | Portrat of a Madchens | Madonna and Child with St Anne and the Young St John |

George John Pinwell,RWS
1842-1875 English illustrator and painter. He was born in humble circumstances and was largely untrained. He was briefly a student at St Martin's Lane Art School and at Heatherley's. From 1863 he contributed woodblock illustrations to magazines, establishing his reputation in 1865 with the Dalziel brothers' editions of The Arabian Nights and The Works of Oliver Goldsmith. Pinwell's finest drawings were commissioned for the Dalziels' poetry gift-books. With another illustrator, John William North (1842-1924), he worked at Halsway Manor in Somerset in 1865, experimenting with formal effects based on the structure of stone farm buildings or on the wooden beams of barn interiors (his drawings do not seem to have survived). Some of the illustrations for A Round of Days (1866) and Wayside Posies (1867) present an ideal vision of the countryside, but a vein of social concern is also present. In The Journey's End, from Wayside Posies, a strolling player lies dead, worn out by hardship and hunger. For an illustrated edition of Jean Ingelow's Poems (1867),
John Maler Collier
(27 January 1850 - 11 April 1934), called 'Jack' by his family and friends, was a leading English artist, and an author. He painted in the Pre-Raphaelite style, and was one of the most prominent portrait painters of his generation. Both his marriages were to daughters of Thomas Henry Huxley. He studied painting at the Munich Academy where he enrolled on 14 April 1875 (Register: 3145) at the age of 25. Collier was from a talented and successful family. His grandfather, John Collier, was a Quaker merchant who became a Member of Parliament. His father (who was a Member of Parliament, Attorney General and, for many years, a full-time judge of the Privy Council) was created the first Lord Monkswell. He was also a member of the Royal Society of British Artists. John Collier's elder brother, the second Lord Monkswell, was Under-Secretary of State for War and Chairman of the London County Council. Collier's first wife, Marian Huxley, 1883In due course, Collier became an integral part of the family of Thomas Henry Huxley PC, sometime President of the Royal Society. Collier married two of Huxley's daughters and was "on terms of intimate friendship" with his son, the writer Leonard Huxley. Collier's first wife, in 1879, was Marian (Mady) Huxley. She was a painter who studied, like her husband, at the Slade and exhibited at the Royal Academy and elsewhere. After the birth of their only child, a daughter, she suffered severe post-natal depression and was taken to Paris for treatment where, however, she contracted pneumonia and died in 1887. In 1889 Collier married Mady's younger sister Ethel Huxley. Until the Deceased Wife's Sister's Marriage Act 1907 such a marriage was not possible in England, so the ceremony took place in Norway. Collier's daughter by his first marriage, Joyce, was a portrait miniaturist, and a member of the Royal Society of Miniature Painters. By his second wife he had a daughter and a son, Sir Laurence Collier KCMG, who was the British Ambassador to Norway 1941-51.
